crypto: caam - Pad SG length when allocating hash edesc
Because hardware will read in multiples of 4 SG entries, ensure the allocated length is always padded. This was already done by some callers of ahash_edesc_alloc, but ahash_digest was conspicuously missing. In any case, doing it in the allocation function ensures that the memory is always there.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
